There are certainly insurance carriers and policies that will not cover any driver not specifically named in the policy. Other relevant facts include where the “other driver” resides and if they are related to the insured. In general, if someone is living in the insured’s household and regularly drives the insured’s vehicle, many insurance carriers expect you to have that person named on the policy. They will need to undergo the same underwriting and qualification process as any other policyholder.
You’ll notice that none of that liability coverage pays for your car or injuries, nor for any injuries your passengers sustain if you cause a wreck. This is why many people — particularly those whose car isn’t yet paid off — want “full coverage” car insurance. This isn’t actually a type of coverage, but instead typically refers to policies that include liability coverage, plus comprehensive and collision coverages.
Drive Other Car insurance is similar to an Individual Named Insured Endorsement. If you need to borrow, test drive, rent, or lease a vehicle, Drive Other Car insurance will extend the coverages you’ve purchased for your commercial auto insurance policy - like Liability insurance, Physical Damage insurance, Medical Payments, and Uninsured Motorist Insurance, to a non-owned car.
